This invention relates to a novel and improved form of wheel,particularly one adapted for use with neumatic tires. The novel featuresof the invention will be best understood from the following descriptionand annexeddrawing, in which I have shown a selected embodiment of theinvention, and in which: Fig. l is a fragmentary section through a wheelrim and the tire mounted thereon.

Fig. 2 is a view on the same plane as Fig.

1, but showing the relation of the rim to a tire whilethe tire is beingput in place or removed.

Fig. 3 is a view showing a preformed inner tube adapted for use withthis invention.

Fi 4 is a view similar to Fig. 3 showing a difi erent form of innertube.

The use of pneumatic tires, particularly as at present employed,materially increases the diameter of the wheels on which they areplaced, which means that if for any reason a tire becomes deflated, theeffective diameter of the wheel'is materially reduced and if thedeflation takes place suddenly, as by a blowout, thevehicle on which thewheel is mounted is placed in a dangerous condition, especially ifoperating athigh speed. This'danger is increased by the fact that thepresent tendency is to use tires of greater size than hitherto and, ofcourse, when a vehicle is a heavy one, the tire is also one which verygreatly increases the diameter of the wheel upon which it is mounted.

According to my invention, I materially reduce the danger which flowsfrom a deflation of the tire by having one side of the rim of largerdiameter than the otheror'by mounting within the space surrounded by thetire a 0 rigid member projecting outwardly from the rim into the spacesurrounded by the tire or by both methods so that upon sudden deflation,or deflationfrom a slow leak. .for instance, the wheel will run uponthis larger diameter side of the rim or upon this project1on, the outerportion of the projection determining the effective diameter of thewheel. It will also be seen that the injury to the tire itself due torunning deflated will be mate rially decreased.

ground without 'a radical di -case of deflation.

Referring now to the drawing, I have shown a wheel having a rim- 1 withopposite sides 2 and 3 thereof of difi'erent diameters, in this instanc,the side 3 having the greater diameter. On the side 3 is provided a seat4 upon which rests one edge portion or head 5 of a tire having a treadportion 6. The side 20f the rim is llkewise provided with a seat 7 uponwhich rests the other edge or head portion 8 of the tire. It will beseen that the tire is made of special form so that oneedge or bead is ofgreater diameter than the other, the bead of greater diameter beinglocated adjacent the tread portion of the tire with substantially noside wall between it and the tread portion, whereas on the other side ofthe tire there is a side wall between the bead 8 and the tread portion 6similar to the usual side wall. The difference in diameter of the twosides of the rim is thus of a substantial amount, so that in efiect alarge part of the tire is eliminated and the rim on one -side is broughtup close to the tread of the tire so that, in case of collapse of thetire, this side of the rim in? engage the erence in diameter between thetread and the rim. The edge portion 8 may be held in place on its seatby means of a removable'ring 9 which may be detachably secured in placeby lugs or bolts inthe usual manner. The bead portion 5 may beconveniently held in place by a stationary ring 10 integral with therim. The tread 6 as shown partially protects the shoulder of the rim 10from injury due to striking any projecting object. It may of coursecover and protect the rim entirely, or

it maybe shaped to a more uniform are on the inside if desired. IDisposed in the spacefsurrou'nded by the tire is an outwardl extendingprojection 11,

this projection being rigid and preferably 7 equal to or greater thanthat side of the rim that is of larger diameter than the other side.

It may be solid as shown, or of thin sections to save weight, and may beof one or several assembled parts. It may be of cast, forged, or weldedmetal, or of composition material. This projection is shown as beingbetween the seats 4 and 7, and between the seat 4 and the projection isan inwardly extending recess 12, the bottom of which is of a smallerdiameter than that of the seat 4. Preferably both the projection and therecess are of annular form extending completely around the rim, as willbe understood by those skilled in the art.

Referring now to Fig. 2 in particular, it will be seen that the placingof the projection 11 within the tire will not prevent easy assemblageand removal, this being'true because of the fact that the recess 12 isprovided. The ring 9 may be removed as indicated in Fig. 2, and then thetire may be moved bodily to the left of Fig. 2 until the edge portion 5passes into the recess 12. That will permit the edge portion 5diametrically opposed to the. part within the recess to be movedoutwardly past the end of the projection'11 as shown at the bottom ofFig. 2. The tire may then be removed by bending it sufliciently to haveit pass over thecircular projection 11. Of course, in placing the tireon the rim, a reverse operation is employed.

The tire is provided with the usual inner tube 13 which may be inflatedin the usual manner, as by a valve 14 passing through the rim and intothe inner tube at the bottom of the recess 12. Of course, the valve maybe placed in any other convenient location. It will be seen that theinner tube being flexible, as is well known in the art, will {ollow thecontour of the inner wall of the re and of the rim, and whendeflation-takes place, for any reason, the load is at once transferredto the projection 11, thereby preventing any serious reduction in theeffective diameter of the wheel. 7

The inner tube may be preformed to fit the shape of the rim and itsprojection as shown at 13, or may be in two parts as shown at 13 and 13,as may be most convenient. In case the forms shown in Fig. 4 are used,of course, suitable openings in the rim will be provided for the passageof the necessary number of v ves 14.

While I have shown the invention as enibodied in a certain form, it is,of course, to

be understood that it may be embodied in claims.
